Found this cool old pull behind xylophone toy today. It is a Fiher Price "pull-a-tune". It still works well, has two strikers at each axle that alternately lift up from underneath to chime as it pulls along. Pretty neat. The copyright is 1964, not sure of actual date of this item but figure probably mid-late 60s early 70s? No idea of it's value but I thought it was a fun piece.
